Description

Technical Field

[0001] The utility model relates to the technical field of canvas processing, and specifically relates to a warping mechanism for canvas processing. Background Art

[0002] Warping is a process of parallel winding a certain number of warp yarns on a warp beam or a loom beam according to specified lengths and widths.

However, the existing winding rollers are mostly directly connected to the device, which causes inconvenience for the staff to disassemble and assemble the winding roller.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0049] Embodiment 1

[0050] Refer to Figures 1-4 , a warping mechanism for canvas processing, including a frame assembly 1, and the frame assembly 1 includes: a bottom plate 11, on the top of which support columns 12 are symmetrically arranged; a replacement assembly 2 is arranged on the bottom plate 11 and the support columns 12, and the replacement assembly 2 includes: a cover body 21, one end of which is symmetrically rotatably connected to the top of the support column 12 through a torsion spring; a connecting plate 211 arranged on the front side wall of the cover body 21; a cavity 22 symmetrically opened on the top of the support column 12; a winding roller 23 arranged between the cavities 22; a connecting block 24 symmetrically and fixedly connected to both ends of the winding roller 23; a convex block 241 fixedly connected to the outer side wall of one of the connecting blocks 24; a motor 251 arranged on the support column 12 on the side close to the convex block 241, and the output shaft of the motor 251 penetrates and extends into the cavity 22; a connecting block 25 fixedly connected to the motor 251, and a groove is arranged on the connecting block 25, which is adapted to the shape of the convex block 241; a cylinder 261 fixedly connected to the top of the bottom plate 11; a lifting plate 26 fixedly connected to the top of the cylinder 261; a limiting mechanism 27 is arranged on the connecting plate 211 and the support column 12. The limiting mechanism 27 includes: a cavity 271 arranged on the side of the connecting plate 211 close to the support column 12; limiting rods 272 symmetrically opened on the support column 12; push rods 273 symmetrically arranged in the limiting rods 272, and one end of the push rod 273 penetrates and extends to the outside of the support column 12; a push plate 274 fixedly connected to the end of the push rod 273 located outside the support column 12; a cross bar 275 fixedly connected to the other end of the push rod 273; a spring 276 fixedly connected between the inner side wall of the limiting rod 272 and the cross bar 275, and the spring 276 is sleeved outside the push rod 273. A tensioning assembly 3 is arranged on the bottom plate 11, and the tensioning assembly 3 includes: a bracket 31 fixedly connected to the top of the bottom plate 11; lead screws 32 symmetrically and threadedly connected to the bracket 31, and the bottom ends of the lead screws 32 penetrate and extend below the bracket 31; a turning handle 33 fixedly connected to the top of the lead screws 32; a guide ring 34 rotatably connected to the bottom of the lead screws 32.

[0051] In use, the staff passes one end of the yarn through the guiding ring 34 in the tensioning assembly 3 and then fixes it inside the winding roller 23. Start the motor 251, and the motor 251 drives the second connecting block 25 to rotate. Since the convex block 241 on the first connecting block 24 is inserted into the groove on the second connecting block 25, the second connecting block 25 can drive the first connecting block 24 and the winding roller 23 to rotate. The winding roller 23 winds the yarn around the winding roller 23. After warping is completed, the staff releases the limit on the cover body 21 through the limiting mechanism 27, so that the first connecting block 24 in the first cavity 22 is exposed: The staff pushes the push plate 274 towards the side close to the support column 12. The push plate 274 drives the push rod 273 and the cross bar 275 to move towards the side away from the groove of the limiting rod 272, and the spring 276 is stretched. When the cross bar 275 completely moves out of the groove of the limiting rod 272, the torsion spring compressed after closing the cover body 21 drives the cover body 21 and the connecting plate 211 to bounce open, facilitating the exposure of the internal structure of the first cavity 22. At this time, start the cylinder 261, and the cylinder 261 drives the lifting plate 26 to move upward. The lifting plate 26 jacks up the top winding roller 23 and the warped yarn upward. The convex block 241 disengages from the groove of the second connecting block 25, so that the first connecting block 24 moves out of the first cavity 22, facilitating the staff to transfer the winding roller 23. Then, the first connecting block 24 with the convex block 241 on the new winding roller 23 is flipped to align with the second connecting block 25, so that the convex block 241 corresponds to the groove of the second connecting block 25. Then, the first connecting block 24 and the second connecting block 25 are connected. Manually turn the cover body 21 to close. After the limiting rod 272 on the connecting plate 211 enters the second cavity 271, the limiting mechanism 27 restricts the limiting rod 272 to realize the closing of the cover body 21: When the limiting rod 272 extends into the second cavity 271, the inclined surface at the bottom of the limiting rod 272 contacts the top of the cross bar 275 and pushes the cross bar 275 towards the side away from the push plate 274. The spring 276 is stretched. When the connecting plate 211 rotates to the horizontal state, the groove on the limiting rod 272 and the cross bar 275 are on the same horizontal line. The elastic force generated after the deformation of the spring 276 pulls the cross bar 275 into the groove of the limiting rod 272, realizing the limitation of the limiting rod 272 and achieving the effect of locking the cover body 21, which is convenient and fast. The tensioning assembly 3 adjusts the tightness of each yarn during the winding process, so that the yarn is in a state with a more appropriate tension: When the tightness of a certain yarn needs to be adjusted, the staff rotates the turning handle 33, and the turning handle 33 drives the lead screw 32 to rotate. The lead screw 32 drives the guiding ring 34 to rise or fall according to the different rotation directions of the turning handle 33, realizing the appropriate adjustment of the tightness of the yarn passing through the guiding ring 34.

[0052] Embodiment Two

[0053] On the basis of Embodiment One, an auxiliary function is added.

[0054] Refer to Figures 1-4 , two sets of the limiting mechanisms 27 are symmetrically arranged. The top of the jacking plate 26 has an arc surface. Symmetrically arranged sliding grooves 4 are formed in the inner side walls of the limiting rods 272, and both ends of the cross rod 275 extend and are slidably connected in the sliding grooves 4.

[0055] Two sets of the limiting mechanisms 27 are provided, so that the two cross rods 275 and the limiting rods 272 cooperate with each other to limit the cover body 21, increasing the firmness of the cover body 21 being limited after being closed. The arc surface on the jacking plate 26 increases the contact area between it and the warping completed winding roller 23, increasing the stability of the winding roller 23 when being jacked up, and facilitating the staff to replace the winding roller 23 in time. When the cross rod 275 moves under the influence of the push rod 273 or the limiting rod 272, both ends of the cross rod 275 slide in the sliding groove 4, and the sliding groove 4 restricts the sliding track of the cross rod 275, preventing the situation that the cross rod 275 is skewed when moving, which affects its normal entry into or detachment from the groove in the limiting rod 272.
